dht11-temp

What This Skill Does

The dht11-temp skill is a specialized OpenClaw agent capability designed to interface directly with DHT11 temperature and humidity sensors connected to a Raspberry Pi's GPIO pins. This skill enables your AI agent to bridge the gap between digital intelligence and physical environment monitoring. It captures raw sensor data, translates the digital signal into human-readable temperature (Celsius) and humidity (percentage) readings, and presents them in a structured format suitable for further analysis or reporting. By utilizing the RPi.GPIO library, the skill provides a stable and reliable interface for hobbyist and industrial IoT applications alike.

Installation

To get started, ensure your hardware is correctly wired with a 10K pull-up resistor between the DATA and VCC pins. First, install the required system dependency: pip3 install RPi.GPIO. Once the dependency is met, you can pull the skill into your OpenClaw environment by executing: clawhub install openclaw/skills/skills/noahseeger/dht11-temp. Ensure your user has sufficient permissions, as accessing GPIO pins usually requires sudo privileges. You can verify the installation by checking the skill path in your local repository.

Use Cases

This skill is perfect for home automation enthusiasts wanting to trigger climate control systems based on real-time data. It is also excellent for server room monitoring, where tracking environmental fluctuations is critical for hardware health. Use it to log daily fluctuations in a home office or to send alerts when humidity levels exceed a threshold, ensuring your environment remains optimal for both hardware and human comfort.

Example Prompts

1. "Check the current temperature and humidity in the room using the dht11 sensor."
2. "What is the humidity reading from the sensor on GPIO pin 4?"
3. "Log the current environment data to my local sensor file and let me know if it's getting too hot."

Tips & Limitations

The DHT11 sensor has a moderate accuracy range and is intended for non-critical monitoring. Because the sensor requires precise timing to read data, ensure your system load is not excessively high when capturing readings. The default pin is set to 19, but you can override this via the DHT_PIN environment variable, which is highly recommended for multi-sensor setups. Always ensure the pull-up resistor is present; without it, you will likely receive read errors or no data at all. Avoid placing the sensor near heat-generating components on your Pi.
